RECEPTACLE AND METHOD OF MAKING THE SAME.

Application filed February 7, 1922. Serial No. 534,646.

My improved receptacle, in a preferred form thereof, is a bilge barrelhaving metal heads provided with peripheral channels in combination witha paper fibre board or pulp board body formed from strips or ribbonswound in the respective channels and then spirally in oppositelyexpanding sections whose ends are brought together in a butt joint whichis lapped internally by a metal ring or band and externally by alaminated paper ring or band.

The object of the invention is, generally stated, to provide areceptacle that is inexpensive, strong, durable, tight and easilyhandled,

I by a simple operation.

Characteristic dcsiderata attained are the provision of a receptaclehaving a paper body, particularly a spirally wound paper body, with asatisfactory head that can be securely fixed therein in tight relationby a simple oporation, and the provision of such receptacle in the formof a barrel with adequate strength at its median section of greatestdiameter together with a joint at such section which will remain tight.

In the accompanying drawings, Fig. 1 is a plan of an end of a receptacleembodying improved features of the invention; Fig. 2 is a longitudinalsectional view through the improved receptacle in the form of a barrelin illustration of a preferred form thereof, and Fig. Cl illustrates acentral section taken through the dissociated parts of the head.

The invention, in the form illustrated, has the heads 1 provided withthe peripheral channels 2, which are conveniently and economicallyproduced from firmly connected conforming bulged circular sections 1 and1 having the respective oppositely projecting peripheral legs or flanges2 and 2 provided i with the respective outwardly projecting lips orflanges 2 and 2, these parts being pressed to shape from sheet metal.The sections l and 1 of each head contain the respective registeringholes 1 and 1 through which are forced a bushing 3 provided with theflanges 3. The latter bears against the surface of the section 1 formingthe inner surface of the head and the sections 1 and 1 are boundtogether thereby with the provision of a charging and dischargingopening.

The body 4 of the receptacle comprises the two sections 4 offrusto-conical form having their sinaller ends locked in the peripheralchannels 2 of the respective heads 1 and their abutting larger endslapped by the conforming interior ring or band 5 and by the exteriorring or band 6, the ring 5 preferably being made of metal withoppositely converging sections to conform with the ends of the bodysections engaged thereon as shown.

The sections 4 are formed by first winding paper, fibre board or pulpboard, strips of suitable width first in the respective channels 2 ofthe heads 1 so as to fill such channels, and then spirally to producethe frusto-eonical sections 4, the term paper being used generically toinclude fibre board and pulp board. The sections thus formed arecombined with the ring 5, on which the larger ends of such sections areeither forced by a telescoping movement or wound, and the butt jointthus formed is wound with. multiplied laminations 6, the laminationsbeing of the number requisite to provide the necessary strength,

It will be understood that the strips may be treated with an adhesive tobind the circular windings to the heads and together and the spiralwindings together, and that the finished barrel may be treated, soakedor painted with water-proofing or protecting material.

It will also be understood that the construction shown, by way ofillustrating a de sirable embodiment of my invention, may be changed, asby forming the heads proper of unitary instead of built up constructionsand by producing receptacles in the form of tubs with a bottom or singleend as by separating the two sections 4* at their butt joint.

IVhile I have shown and described a preferred form of my invention, I donot desire to be limited to the details of construction excepting asspecified in the claims,as my invention comprehends broadly the buildingup of a receptacle body upon a head, with elimination of the usualoperations required and defects involved in assembling the heads andbodies or inserting and securing heads in bodies as previouslypracticed.

Having described my invention, I claim 2- 1. A receptacle having a headprovided with a peripheral channel and a spirally wound body providedwith an end comprising a flat helix locked in said channel.

2. A receptacle having a body comprising a spirally wound strip 0Vegetable sheet material with a portion of such strip wound in a flathelix around a head having a peripheral flange interlocked with saidstrip.

3. A bulged receptacle comprising a head with peripheral locking meansforming a channel of greater width than the thickness of said head and abody comprising a narrow strip of sheet material wound on said head ininterlocking relation with said locking means and forming a conoidalhelix of varying cross section projecting from said head.

4. A barrel having spirally wound abutting sections, means lapping theinterior and exterior of the members forming the joint between saidsections, and heads forming peripheral channels interlocked with theopposite ends of said sections, said sections having shouldersprojecting therefrom and engaged in said channels.

5. A barrel having sectional heads forming Eeripheral flanges and aspirally Wound body aving laminations engaged by said flanges.

6. A receptacle having a metal head comprising a plurality ofregistering disks provided with oppositely disposed peripheral flangesand a paper body having laminations wound on said flanges.

7 A receptacle having a head comprising a plurality of conforming bulgeddisks hav ing oppositely projecting peripheral members with flangesthereon forming a circumferentially open channel between them.

8. A receptacle having a head comprising a plurality of conforming metaldisks having oppositely projecting peripheral flanges with lips thereonforming a circumferentially open channel, said disks containingregistering holes, and a bushing set in said holes.

9. A receptacle having a spirally wound paper body comprising abuttingsections havmg shoulders thereon, heads including peripheral channelsengaged on said shoulders, and a metal ring Within said body and lappingthe joint between said sections.

10. A receptacle having a spirally Wound paper body comprising abuttingsections, paper laminations wound on said body so as to lap the jointbetween said sections and heads forming a peripheral channel forengaging a shoulder in said body, and a ring within said body andlapping the joint between said sections.

11. A rece tacle comprising a spirally coiled strip of sheet materialforming a body having a collar projecting therefrom of greater radialthickness than the remainder of said body and a sectional head havingradially projecting members engaging said collar between them.

12. A receptacle comprising a head having peripheral members eachprovided with a radial flange forming a circumferentially open channeland a splrally Wound sheet material body having a flat helical collarengaged between said flanges and filling said channel.

13. The method of making bilged receptacles which consists in providinga head with peripheral locking means forming a channel of greater widththan the thickness of said head and winding thereon a narrow strip ofsheet material in a conoidal helix to form a body on said head ininterlocking relation with said locking means, said body varying incross section.

14. The method of making receptacles which comprises Winding narrowstrips of sheet material in conoidal helixes to form flaring bodysections, telescoping a pair of body sections upon a convex ring, andWinding a reenforcing band of sheet material around the joints betweensaid sections.

15. A barrel having a spirally wound body consisting of abuttingsections secured by interior and exterior members, and sectional headsforming a peripheral flange for engaging a shoulder on each of saidsections.

16. A receptacle including a head having a peripheral flange forming achannel of greater width than the thickness of said head, and a spirallyWound strip of sheet material forming a body having a collar engagingsaid flange.

17. The method of making rece tacles which comprises winding about aflanged head narrow strips of sheet material in conoidal helixes to formflaring body sections, telescoping a pair of body sections upon aconvexring, and winding a reenforcing band of sheet material around the jointsbetween said sections.

In testimony whereof I have hereunto set my name this 4th day ofFebruary, 1922.

MATHIAS R. KONDOLF.
